Kestrel is the world’s leading brand for portable weather meters. Since 1996, parent company Nielsen-Kellerman has been designing and manufacturing compact handheld instruments at its facility in Boothwyn, Pennsylvania, that precisely measure wind speed, temperature, humidity, barometric pressure and dozens of additional environmental parameters. Whether on the shooting range, during wildfire operations, in agriculture or on a mountain expedition – Kestrel meters deliver reliable data under extreme conditions. At Swiss-Sale.ch you will find selected Kestrel Pocket Weather Meters for outdoor, hunting and professional applications.
Kestrel’s product range is organised into clearly tiered series. The basic models Kestrel 1000 to 3500 measure wind speed, temperature and humidity – ideal for outdoor enthusiasts, sailors and sport shooters. From the Kestrel 4000 upwards, barometers, data loggers and expandable interfaces are added. The 5000 series offers the full spectrum of environmental readings including dew point, heat index, wind chill and altitude measurement. Specialised models such as the Kestrel 5500 Fire Weather and the Kestrel 5700 Ballistics with Applied Ballistics integration are aimed at professionals in firefighting, military and precision shooting.
Nielsen-Kellerman was founded in 1978 by Richard Kellerman and Paul Nielsen – originally with a focus on rowing electronics. In 1996 the company launched the first Kestrel weather meters: the models 1000, 2000 and 3000. Firefighters across the USA immediately adopted them to replace their analogue weather kits. Today the Kestrel range measures over 20 environmental parameters, is IP67 waterproof and MIL-STD-810G drop-tested. Manufacturing takes place exclusively at the Boothwyn, Pennsylvania facility – with NIST-traceable calibration and lifetime service support.
All Kestrel meters are IP67 rated for dust and water ingress: they survive full submersion to a depth of 1 metre for 30 minutes. The housing meets the military standard MIL-STD-810G for shock and drop resistance. The patented impeller sensor is user-replaceable and enables accurate wind measurement from as low as 0.6 m/s. Whether in driving rain at high altitude, during desert sandstorms or at minus 29 °C – Kestrel delivers reliable readings when other instruments have long since failed.
Selected Kestrel models feature LiNK Bluetooth technology, which enables wireless transmission of measurement data to smartphones, tablets and computers. Combined with the Kestrel LiNK app, readings can be monitored in real time, data series recorded and exported. For stationary measurements, Kestrel also offers the DROP system – compact data loggers that communicate wirelessly with the Kestrel meter and can be positioned at remote locations.
Kestrel meters are deployed wherever precise environmental data are critical. Precision shooters and snipers use the Kestrel 5700 with Applied Ballistics for accurate firing solutions at over 1,000 metres. Firefighters rely on the Kestrel 5500FW for fire danger indices. Farmers use the Kestrel 5500AG for optimal spray conditions. Mountaineers, hunters and outdoor enthusiasts value the compact 3500 and 5000 models for weather forecasting and altitude measurement on the move.
